Minimum COF / PF Value
As a safeguard, the COF/PF can be prevented from dropping below a certain point. This point is the
Minimum COF/PF value.
Maximum COF / PF Value
The Maximum COF/PF can also be entered as a safeguard.
COF / PF Adjustment Mode
This selection determines if changes to the COF/PF will be made automatically or if the instrument will
monitor the conditions without making any changes. When in Monitor mode, a COF/PF will continue to be
suggested, but no modifications will be made to the atmosphere controller.
Minimum Temperature for sampling (0 = disabled)
This value is the lowest temperature that the instrument will sample from. When the temperature drops
below this value, the COF/PF adjustment will stop and the sample pump will turn off only if the pump is
set to “Auto” mode (see the Pump Control section on page 19). To use this feature, the instrument should
be communicating with an instrument that can provide real-time temperature data. The purpose of this
function is to prevent the instrument from pulling a bad sample, which could potentially damage the
sensors. The minimum temperature should always be slightly higher than the lowest possible process
temperature.
Minimum Millivolts for sampling (0 = disabled)
This value is the lowest number of millivolts at which sampling will take place. When the number of
millivolts drops below this value, the COF/PF adjustment will stop; the sample pump will turn off only if
the pump is set to “Auto” mode (see the Pump Control section on page 19) and the Minimum Millivolt
Condition is set to “Also stops pump” (see below). To use this feature, the instrument should be
communicating with an instrument that can provide real-time probe millivolt data. The purpose of this
function is to prevent the instrument from pulling a bad sample, which could potentially damage the
sensors. This will prevent adjustments from being made when the proper conditions are not met. The
minimum millivolts set point should be slightly higher than the minimum millivoltage that is expected.
Minimum Millivolt condition (0 = disabled)
This determines the behavior of the MGA 6010 when the minimum millivolts value is reached. Two
settings are available:
• Also stops pump. When this setting is selected, the sample pump will be stopped if the pump is
set to “Auto” mode (see the Pump Control section on page 19), and COF/PF adjustment will be
stopped.
• Only inhibits adjust and control. When this setting is selected, COF/PF adjustment will be
stopped, and the sample pump will be allowed to run.
To use this feature, the instrument should be communicating with an instrument that can provide real-
time probe millivolt data. This is another feature that is intended to prevent the analyzer from pulling a
bad sample and potentially damaging the sensors.
